Rhythm And Hues and The Mill’s VFX wizzes talk The Daily through Snow White’s two grandstand visual sequences in this clip, the bridge troll and magic mirror. Other effects houses were brought on by Rupert Saunders to design further sequences, including Double Negative who, as VFX supervisor John Moffat tells The Art Of VFX, were charged with bringing the movie’s flying goth, the Bat Fairy, to life. “It was originally designed and built for a trailer shot, [but] Rupert liked the creature and asked if we could use it in a few shots on the actual film. It was essentially a fully CG animated creature that was taken from concept to final shot for the trailer in three weeks.”
